OLED micro display structure and device thereof

The invention relates to an OLED micro display structure which sequentially comprises an OLED light-emitting layer, an insulating layer, a conductive layer, a grounding layer and a silicon-based layerfrom top to bottom. The OLED light-emitting layer comprises an OLED pixel which at least comprises three color sub-pixels; wherein a certain distance is reserved between every two adjacent OLED pixels, and a gap region is formed between every two adjacent OLED pixels; the conductive layer is located right below the gap region and is connected with the grounding layer; the insulating layer is located between an OLED pixel anode and the conductive layer; and the ratio of the coplanar capacitance of the anode between two adjacent OLED pixels to the ground capacitance of a flat plate between theanode of the OLED pixel and the grounding layer is less than 0.1. The OLED micro display structure has the advantages that the insulating layer which is thin enough is additionally arranged between the conductive layer and the
